Regression on components with inputs using a transform function

[mlz11]

Hello 👋🏻,

I believe I encountered a regression after bumping the package @testing-library/angular from v17.1.0 to v17.2.1 while trying to use the new inputs property.

The issue arises with components that have inputs using a transform function that changes the type, such as:

 title = input.required<TitleObject, string>({
    transform: toTitleObject,
  });

Below is the test I wrote :

it('should render', async () => {
    await render(ChildComponent, {
      inputs: {
        title: 'title',
      },
    });
  });

In this case, TypeScript raises an error on the render function 🔴:

Type 'typeof ChildComponent' is not assignable to type 'string'.

When modifying the input so that it has the same type as after the transformation, the TypeScript error is resolved, and the test passes 🟢:

it('should render', async () => {
    await render(ChildComponent, {
      inputs: {
        title: {title: 'title'},
      },
    });
  });

Please find a reproduction sample below:

If this is confirmed as a bug, I would love to contribute to resolving it.

Thanks for your help!
